Among the figure as seen: frame 1, the extruding gear 2, the gear teeth 3, through hole 4, gear shaft 5, engine 6, between cog through hole 7, tooth top through hole 8, flank through hole 9, increment face 10, root circle 11, tooth root 12, dedendum angle 13, root fillet 14, gear reducer 15, cooling water pipe 16, gear-bearing 17.
The specific embodiment
First kind of embodiment: shown in Figure 2 as Fig. 1; the frame 1 of this living beings tooth mould particle pressing machine is equipped with a pair of intermeshing extruding gear 2 by two gear shafts 5; 2 one-tenth of gears of extruding are cylindric, and between the gear teeth 3 of extruding the gear 2 and both sides of the gear teeth 3 have a plurality of through holes 4.During work, extruding gear 2 relatively rotates under the drive of engine 6, and the biomass material of pulverizing feeds a pair of gear meshing portion, can be extruded as granular fuel closely from through hole 4.Its improvement is: the gear teeth top end face upper edge radial inward at extruding gear 2 has a plurality of through holes 4, is called tooth top through hole 8.The effect of this tooth top through hole 8 is: when the tooth top of a gear during near the tooth root of another gear, material both can be extruded between cog through hole 7, also can extrude from tooth top through hole 8.Be equivalent to increase the passage that material is extruded, operating efficiency significantly improves.
Here preferably staggered in the position of tooth top through hole 8 and between cog through hole 7, effect can be better.Certainly, also can on same gear, only have wherein a kind of through hole.
Experiment showed, the facility that adopted this porous gear, originally the fault of the distortion of between cog solid accumulation and gear shaft or gear damage initiation disappears substantially, and the facility working stability can be worked continuously more than 300 hours.Type with 1.5 tons/hour of productivity ratio is example; used motor only is 30KW; than market reaction preferably the ring mode granulator reduced by 73.2% on year-on-year basis; the quality of the granular fuel of compression meets the requirements; break through the high bottleneck of stalk compressed fuel power consumption cost, be subjected to sample plot peasant's favorable comment deeply.
Second kind of embodiment: shown in Figure 7 as Fig. 5 Fig. 6, have between cog through hole 7 on the root circle 11 between the gear teeth of extruding gear 2, tooth top has tooth top through hole 8, and gear teeth both sides have flank through hole 9.The center line of the flank through hole 9 on the intermeshing gear teeth staggers mutually.In conjunction with Fig. 7 as seen, the between cog through hole 7 outmost two exceeded extruding gear 2 increment faces 10, in general should surpass half hole.Can certainly adopt the hole of other shapes.This structure also can be understood as removes a fritter to the gear teeth two ends of extruding gear 2 from the part of root circle more than 11, and makes the outer face 10 of the outmost between cog through hole 7 outstanding gear teeth.Though the variation of this structure is very little,, the material that extrude at extruding gear 2 two ends can be extruded from these two between cog through holes 7, avoids the two ends solid accumulation to hinder the normal operation of extruding gear 2.
The third embodiment: as shown in Figure 8, as seen push the dedendum angle 13 of gear 2, just the tooth root 12 of the gear teeth and the angle of cut α between the root circle 11 are wedge angle.Wedge angle can be 〉=90 ° angle, and can certainly be≤90 ° angle, but not be that circular arc connects.In conjunction with Fig. 9 as seen, the intersection of the tooth root of all gears and root circle is arc transition at present, visible root fillet 14 on end face.Experiment showed, this root fillet 14, the cutting performance of the gear teeth is bad, root fillet 14 is removed in the easy adhesion of material, just removes the part of Fig. 9 tooth root blacking, tooth root 12 has namely become wedge angle with root circle 11 and has been connected, and is sharper, eliminated the material adhesion phenomenon.
Because variation has taken place in many shapes of extruding gear 2, so master gear originally has not been optimal selection.Therefore, recommend to adopt the nonstandard gear of following parameter: number of teeth 17-100, the extruding gear of modulus 8-50 is compared with master gear, its root diameter increases 2-25mm successively with modulus, tooth depth reduces 1.5-15mm successively, and the tooth top back lash is 0.1-0.5mm, preferred 0.2mm.Wherein, the number of teeth be 30 extruding gear with the contrast of master gear concrete structure parameter as following table:
The 4th kind of embodiment: shown in Figure 11 as Figure 10, a pair of intermeshing extruding gear 2 is housed on the frame 1 of this living beings tooth mould particle pressing machine, 2 one-tenth of gears of extruding are cylindric, and between the gear teeth 3 and both sides of the gear teeth 3 have a plurality of through holes 4.On two gear shafts 5 of two extruding gears 2, a pair of intermeshing gear reducer 15 is housed also, gear reducer 15 does not carry out the particle squeeze job, its effect mainly contains 2 points: the one, determine two installation sites of pushing gears 2, just limit two gaps between the extruding gear 2, guarantee that two extruding gears 2 can carry out operation under the gap of the best.The 2nd, bear pressure, extruding gear 2 significantly reduces because having a plurality of through hole 4 intensity, damages easily when mutual extrusion, gear reducer 15 has been arranged, can bear big portion transmission pressure, alleviated pressure and the wearing and tearing of extruding gear 2, increase the service life, strengthen the stability of work.
The 6th kind of embodiment: by Figure 12 Figure 13 as seen, extruding gear 2 has three, and middle one, both sides respectively have one.Equally, gear reducer 15 also has three, and structural principle is identical with first kind of embodiment.This example explanation, the form of extruding gear 2 and gear reducer 15 can be diversified, is not limited only to a pair of gear, can spread to three or morely, comprises multiple versions such as planetary gear not of uniform size.
Certainly, adopt the facility of a plurality of extruding gears, its feeding mode also needs corresponding adjustment.Three gears as shown in figure 12, it feeds best axial feeding along gear, also can adopt pressure intake mechanisms such as screw feeder.Because belonging to prior art, do not draw in detail at this.
The 7th kind of embodiment: as shown in figure 14, in the inside of extruding gear 2 cooling water pipe 16 is housed, squeezes into recirculated water during operation, the particle of extruding is cooled off.Existing granulator, excessive because of extruding force, the particle temperature of extruding is very high, approaches or surpass the burning-point of material, occurs carbonization phenomenon often, thereby need promote the particle of extruding to throw down then and dispel the heat, and has strengthened equipment cost and operating cost.These facility extruding force is moderate, and particle temperature is relatively low, and the heat radiation time that needs is shorter., also have the equipment of heat radiation now.Adopted after the recirculated water cooling, can omit the lifting heat dissipation equipment, in discharging, can reach package temperature, simplified the structure, saved the time, reduced cost.
Certainly, the form of cooling water pipe 16 can be diversified.As shown in figure 15, in the gear shaft 5 of extruding gear 2, cooling water pipe 16 is set, can avoids gear-bearing 17 overheated.
Above-mentioned cooling water pipe 16 must interrelate with water source and water pump, could work, and because belonging to prior art, repeats no more.
